Wednesday June 18, Afternoon Update

The warm air has finally broken through into Central Maryland, and the next wave of energy will tap into the high level of humidity in place. Dew points are in the mid-70s, which is very tropical and can result in torrential downpours. As a result, the National Weather Service has posted a Severe Thunderstorm Watch until 7 PM and a Flood Watch until 8 PM for the next round of thunderstorms.

This report will include the live radar and lightning widget to compare to the forecast simulation. Note that the risk for severe storms will increase tomorrow, Thursday. Then, we are set up for an intense heat wave beginning this weekend and lasting into next week.

Flood Watch

  • The counties of Central Maryland include metro Baltimore, Annapolis, and Washington.
  • Rainfall is expected to be between 1 and 2 inches, with some spots receiving up to 3 inches due to slow-moving or repeating storm cells.
  • This may overwhelm local waterways, so creeks and streams can overflow their banks.

June 18 flood watch

UPDATED: SEVERE THUNDERSTORM WATCH UNTIL  7 PM

  • A WATCH will be issued when there is a greater POTENTIAL for severe storms. This will list counties and cover a 4 to 6-hour time window.
  • A WARNING will be issued when A STORM FORMS AND IS BEING TRACKED! This will list towns in the path and is usually a 45-minute window.

RESTATING MY MESSAGE ABOUT DYSLEXIA

I am aware there are some spelling and grammar typos and occasional other glitches. I take responsibility for my mistakes and even the computer glitches I may miss. I have made a few public statements over the years, but if you are new here, you may have missed it: I have dyslexia and found out during my second year at Cornell University. It didn’t stop me from getting my meteorology degree and being the first to get the AMS CBM in the Baltimore/Washington region. One of my professors told me that I had made it that far without knowing and to not let it be a crutch going forward. That was Mark Wysocki, and he was absolutely correct! I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. I also can make mistakes in forecasting. No one is perfect at predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky.  There has been no editor who can check my work while writing and to have it ready to send out in a newsworthy timeline. Barbara Werner is a member of the web team that helps me maintain this site. She has taken it upon herself to edit typos when she is available. That could be AFTER you read this. I accept this and perhaps proves what you read is really from me… It’s part of my charm. #FITF
